A scientist is interested in the effect of time spent with parents and number of hoursyouth spend watching television. The researcher knows that the average teen whose
parents work outside the home spends 20 hours a week watching television. The
population mean = 20 and the standard deviation of the distribution is equal to 5.
Calculate the z-scores for the following individual times:________
If X = 5, z= ________
If X = 37, z= ________

Answers

Answer: If X = 5, z=-3

If X = 37, z= 3.4

Step-by-step explanation:

We know that the formula to find the z-score for any random variable x is given by :-

$z=(x-\mu)/(\sigma)$

, where $\mu$ = Population mean

$\sigma$ = Population standard deviation.

As per given , we have

$\mu=20\n\n\sigma=5$

Then , the z-score for x =5

$z=(5-20)/(5)=(-15)/(5)=-3$

i.e. If X = 5, z=-3

When x =37,then $z=(37-20)/(5)=(17)/(5)=3.4$

i.e. If X = 37, z= 3.4

What is the missing circle sequence number 40,20,?,40,20,10

Answers

40,20,?,40,20,10?
? = 10
Because, the sequence is 40,20,10 and then replay it again

or

40 - 20 = 20
20 - 10 = 10
40 - 20 = 20
20 - 10 = 10

So, ? = 10

It is 10 that ìs missing because the sequence shows that after 20 is 10

What is the period of the sinusoidal function?

Answers

Given y = A sin (Bx + C) + D

amplitude is | A |
period is $\bold{\frac{2\pi}{\text{B}}}$
phase shift is ${-\frac{\text{C}}{\text{B}}}$
vertical shift is D

A cos function is the same as a sin function.

A tan function has a period of π, so the period is $\frac{\pi}{\text{B}}$

Elliott has 4 columns of marbles. He has 3 marbles in each column. How many marbles does he have in all? *

Answers

Answer:

3*4=12

Step-by-step explanation:

the answer is 12

Final answer:

To find out how many marbles Elliott has in total, we multiply the number of columns by the number of marbles in each column, resulting in 12 marbles in total.

Explanation:

To find out how many marbles Elliott has in total, we can multiply the number of columns by the number of marbles in each column. In this case, Elliott has 4 columns with 3 marbles in each column. So, we can calculate the total number of marbles by multiplying 4 and 3, which equals 12. Therefore, Elliott has 12 marbles in total.
